Ndi kupititsa patsogolo chidziwitso cha chilengedwe komanso kufunikira kwa msika wa zida zomangira kuti zigwire ntchito ndi kuteteza chilengedwe, zida zomangira zomwe sizigwirizana ndi chilengedwe zakhala zida zodziwika bwino pantchito yomanga. Cellulose ether, monga zinthu zambiri zama polima, zimagwira ntchito yofunika kwambiri pakupanga zida zomangira zachilengedwe zomwe zimagwira ntchito bwino. Pali mitundu yambiri ya ma cellulose ethers, omwe amapezeka kwambiri ndi hydroxypropyl methylcellulose (HPMC), methyl cellulose (MC), hydroxyethyl cellulose (HEC), ndi zina zotero. , matope osakaniza owuma ndi zokutira poyendetsa madzi, kupititsa patsogolo rheology ndi kupititsa patsogolo zinthu zakuthupi.
1. Makhalidwe a cellulose ethers
Cellulose ether ndi gulu la polima lotengedwa ku ulusi wachilengedwe wa zomera. Amapangidwa sungunuka, thickening, madzi kusunga ndi filimu kupanga kudzera etherification reaction. Makhalidwe ake akuluakulu ndi awa:
Kusunga madzi: Ma cellulose ether ali ndi mphamvu yabwino yosungira madzi, yomwe imatha kuwongolera bwino kutulutsa madzi muzomangamanga, kupeŵa kutuluka kwamadzi mochuluka, motero kumapangitsa ntchito yomanga.
Makulidwe: Cellulose ether imagwiritsidwa ntchito ngati chowonjezera muzomangamanga, zomwe zimatha kukulitsa kukhuthala kwazinthu ndikuwongolera magwiridwe antchito ake pomanga.
Kumamatira: Mumatope osakaniza owuma ndi zomatira, cellulose ether angagwiritsidwe ntchito ngati chomangira kuti apititse patsogolo kumamatira pakati pa zinthu ndi maziko.
Kusintha kwa Rheological: Ma cellulose ether amatha kusintha mawonekedwe a rheological a zomangira, kuti athe kukhalabe ndi madzi abwino komanso thixotropy pansi pamikhalidwe yosiyanasiyana yomanga, yomwe ndi yabwino yomanga ndi kuumba.
Anti-sagging: Ma cellulose ether amatha kukonza zinthu zoletsa kugwa, makamaka popanga makoma oyimirira, omwe amatha kuteteza matope kapena utoto kuti usagwe.
2. Kugwiritsa ntchito cellulose ether muzomangamanga zomwe sizigwirizana ndi chilengedwe
Mtondo wosakanizika wowuma
Mtondo wosakanizika ndi zinthu zomangira zomwe sizimakonda zachilengedwe, zomwe zimagwiritsidwa ntchito kwambiri popaka pulasitala pakhoma, kusanja pansi, kuyala matailosi ndi zinthu zina. Ma cellulose ether amagwiritsidwa ntchito kwambiri mumatope osakaniza owuma, makamaka amasewera kusungirako madzi, kukhuthala ndi kugwirizana. Ma cellulose ether amatha kupanga matope kuti atulutse madzi mofanana panthawi yowumitsa, kuteteza ming'alu yomwe imayambitsidwa ndi kutaya madzi ambiri, ndikuwonjezera mphamvu yomangirira ya matope kuti zitsimikizire mphamvu zake ndi kulimba pambuyo pomanga.
Zopaka zomangamanga
Ma cellulose ether amagwiritsidwa ntchito ngati chowonjezera komanso chosungira madzi muzopaka zopangira madzi kuti apititse patsogolo ntchito yomanga komanso kuyanika komaliza kwa zokutira. Ili ndi mawonekedwe abwino kwambiri opangira mafilimu komanso kusintha kwa rheological, zomwe zimatha kuonetsetsa kuti zokutira zimakhala ndi kufalikira kwabwino pansi pa zida zosiyanasiyana zomangira. Kuphatikiza apo, ether ya cellulose imathanso kuwongolera anti-sagging katundu wa zokutira, zomwe zimapangitsa kuti zisagwedezeke zikagwiritsidwa ntchito pamtunda, potero zimapeza zokutira zofananira.
Zomatira matailosi
Zomata za matailosi ndizofunikira kwambiri pantchito yomanga zomanga zachilengedwe. Ma cellulose ethers amatha kupititsa patsogolo kusungidwa kwa madzi ndi anti-slip properties za zomatira ndikuwonjezera nyonga yomangirira pakati pa matailosi ndi wosanjikiza woyambira. Panthawi yomanga, kuwonjezera kwa ma cellulose ethers kumapangitsa kuti ntchito zomatira matayala zitheke bwino, komanso kuonetsetsa kuti nthawi yayitali yotseguka, yomwe ndi yabwino kwa ogwira ntchito yomanga kuti asinthe.
Putty ufa
Ufa wa putty umagwiritsidwa ntchito kukonza khoma ndi kukonza. Kusungidwa kwamadzi kwa cellulose ether kumatha kuletsa kusweka kapena kugwa chifukwa cha kuyanika kwa putty mwachangu pambuyo pomanga. Panthawi imodzimodziyo, kukhuthala kwake kumathandizira kukonza zokutira ndi kusalala kwa putty, zomwe zimapangitsa kuti zomangamanga zikhale zosavuta.
Zida zodziyimira pawokha
Kugwiritsiridwa ntchito kwa cellulose ether mu zipangizo zodzipangira pansi makamaka kumapangitsa kuti madzi azikhala ndi madzi komanso kusunga madzi, kuonetsetsa kuti zinthuzo zikhoza kugulidwa mofulumira komanso kugawidwa mofanana panthawi yomanga pansi, ndikuletsa pansi kuti zisagwe kapena mchenga chifukwa cha kutaya madzi.
3. Ubwino wa chilengedwe wa cellulose ether
Natural gwero, chilengedwe wochezeka kupanga
Ma cellulose ether amapangidwa kuchokera ku cellulose yachilengedwe ndipo amatha kuwonjezedwanso. Palibe mpweya woipa wowononga ndi zonyansa zomwe zimapangidwira panthawi yopanga, ndipo kukhudzidwa kwa chilengedwe kumakhala kochepa. Kuonjezera apo, poyerekezera ndi mankhwala owonjezera achikhalidwe, cellulose ether alibe vuto lililonse m'thupi la munthu ndipo akhoza kuonongeka mwachibadwa. Ndizinthu zobiriwira komanso zachilengedwe.
Chepetsani kugwiritsa ntchito mphamvu zamagetsi ndikukulitsa luso la zomangamanga
Ma cellulose ether amatha kupititsa patsogolo ntchito yomanga ya zida zomangira, kupanga kuti zomangamanga zikhale zosavuta komanso zachangu, komanso kuchepetsa kuwononga zinthu komanso kugwiritsa ntchito mphamvu. Kuphatikiza apo, chifukwa cha kusungidwa bwino kwa madzi, cellulose ether imatha kuchepetsa kufunikira kwa madzi pomanga ndikusunganso zinthu.
Kupititsa patsogolo kulimba kwa zipangizo zomangira
Ma cellulose ether amatha kupititsa patsogolo kulimba kwa zida zomangira zachilengedwe, kupangitsa moyo wautumiki wa nyumba kukhala wautali, kuchepetsa kufunika kokonzanso kapena kusinthidwa chifukwa cha ukalamba kapena kuwonongeka kwa zida zomangira, potero kuchepetsa zinyalala zazinthu komanso kupanga zinyalala zomanga.
Monga zowonjezera zachilengedwe, zotetezeka komanso zogwira ntchito zomangira, cellulose ether yakhala ikugwiritsidwa ntchito kwambiri m'magawo ambiri omangira okonda zachilengedwe monga matope osakaniza owuma, zomatira matailosi, ndi zokutira zomanga. Sizingawongolere ntchito yomanga yomanga ndikuwongolera zinthu zabwino, komanso zimakhala ndi zabwino zachilengedwe. M'munda wamtsogolo wa zida zomangira, ndikusintha kosalekeza kwa zofunikira zoteteza chilengedwe, chiyembekezo chogwiritsa ntchito cellulose ether chidzakhala chokulirapo.
